Vol 1 CHAPTER 15: Everything I Need to Do to Seduce Her ②【Volume 1: Preparation Arc】

I took the train three stops from my house to visit my older cousin who lived alone.

And the moment I arrived, I practically drove my face into the floor with the force of my prostration.

“Shinichi-nii-chan! Please, please teach me how to have sex!!”

“Get out.”

The person I turned to for knowledge of women was my cousin.

My cousin was, of course, male.

I need to be clear here to avoid misunderstanding: I’m not trying to borrow his body to learn technique. That’s not what this is about.

I’m seeking his guidance for a very specific reason.

“If you don’t help me, I’ll tell your mother that you work in the adult entertainment industry.”

“You little—! Are you seriously trying to blackmail me?! And how the hell do you know that?!”

“Well, that’s a mystery, isn’t it?”

The truth was, my cousin was a specialist when it came to intimate relations with women. There was no way I was passing up the opportunity to learn from him. He was the perfect mentor.

Out of respect for his privacy, I won’t go into detail, but Shinichi-nii-chan had a particular skill: bringing women to orgasm. I’d known about this for a while, but out of family loyalty and a sense of honor, I’d kept it to myself.

“Please, I’m begging you!”

But this situation was desperate. If I went into things with Kotofuki completely clueless, I’d end up embarrassing myself. I needed to learn from him at any cost—how to handle a woman, what she wanted, how to please her.

I stayed in my prostrate position, my forehead pressed firmly to the floor, repeating over and over: “Please, I’m asking you. Please.”

“Sigh… well, I’m glad it was you who found out and not someone else…”

My genuine desperation must have convinced him that this wasn’t a joke. Shinichi-nii-chan began to relent, though his resistance was still evident.

“Look, there are manuals and guidelines I use for work, but those are company property. They’re proprietary. I can’t just hand them out to anyone who asks, no matter how much they beg. You understand that, right?”

“Please, I’m begging you!!”

“Besides, why are you in such a rush anyway?”

Shinichi-nii-chan asked, genuinely puzzled.

“Didn’t you say you got a girlfriend? You two can figure it out together, slowly. Honestly, that’s way better than learning from me—more natural that way.”

He was right, of course. Those things should be explored with a partner you trust.

But I had a reason I couldn’t do that.

“Actually…”

Still looking at the floor, I told him everything.

That Kotofuki had dumped me.

That she’d lost her virginity to my school senpai.

That despite all that, I couldn’t give up—I’d decided to seduce her back.

That to make it happen, I needed to master the art of pleasing a woman.

When I finished, Shinichi-nii-chan was silent for a moment. Then he simply said, “I see…” and placed a hand on my shoulder. He gave it a few hard, encouraging pats before pulling me up to my feet.

“Alright, stand up… don’t just lie on the floor like that forever.”

“Y-Yes…”

“Listen, whatever you’re imagining about ‘making a woman feel good,’ throw that idea away right now. If you’re thinking something like ‘Oh, this’ll be fun’—kill that thought. If you can accept that, then I’ll teach you.”

“Yes! Thank you, nii-chan!”

“This isn’t me training you as some kind of employee. This is just your older cousin doing you a favor—teaching you some pretty questionable techniques.”

With that, he smiled—the kind of reliable smile that made you want to trust him completely. And I cried. I thanked him over and over, expressing more gratitude than I’d ever felt before.

It turned out I had the best cousin in the world.

Once I’d calmed down, Shinichi-nii-chan asked me a question.

“So, this girlfriend of yours… Kotofuki, was it? What’s she like?”

“She’s a little spacey, but she’s my goddess.”

“Idiot, that’s not what I’m asking. Tell me her height, her build, her physical features. Or better yet—show me a photo. I’ll find a girl who looks similar.”

“Huh? Wait, you mean…?”

His words didn’t immediately register. I couldn’t quite grasp what he was saying.

“What are you spacing out for? You want to get good at pleasing women, right? Well, you can’t do that without an actual woman to practice on.”

“So… you’re saying you’ll… find me an attractive older woman to… practice with?”

“That’s exactly what I’m saying.”

I was shocked. “Really?! You’re serious?!”

“Dead serious. Now man up and stop whining. Make a commitment. And I’m warning you—since she’s doing this as a favor to help with your training, you better treat her with respect. If you’re disrespectful for even a second, I’ll beat the shit out of you.”

“O-Of course! I’ll be nothing but grateful and sincere, I promise!”

“Calm down a bit. Anyway, I’ll reach out to someone I have in mind. Once they confirm, I’ll let you know. Keep your schedule clear.”

“Understood! Thank you so much!!”

And just like that, the matter was settled. The unexpected turn of events left me too excited to sit still, and the following days felt endless.

Then came that weekend.

Shinichi-nii-chan called me over to his place.

“Yo, you made it.”

“Y-Yes, I’m here.”

I wanted to respond naturally, but the words wouldn’t come out normally. Walking into my cousin’s apartment, I was visibly tense—stiff with nervousness.

“So… where is she? The woman, I mean?”

“Hmm? Oh, right. Let me introduce you first.”

My question came out awkwardly, and Shinichi-nii-chan let out what sounded like an amused chuckle. He beckoned me toward the back of his apartment.

My feet felt heavy.

Each step felt significant, like I was approaching something crucial. I followed him in a solemn daze. Before long, we’d reached the destination.

A bedroom.

“Act respectfully. This is the woman who’s going to instruct you—”

With that, Shinichi-nii-chan opened the bedroom door.

In the dimly lit room, I saw a silhouette lying on the bed.

As I approached, nervously trying to hide my tension, the figure gradually came into focus.

“Ah—”

A sound escaped my lips involuntarily.

The person before me was stunningly beautiful.

She had perfectly proportioned eyebrows and eyes, skin pale and translucent as porcelain. Her cheeks held a soft flush of color, and her smile was… it was difficult to even describe. And her body—she carried an otherworldly sensuality about her. Every curve was perfectly balanced; every proportion was idealized.

She was positioned in an explicit pose, looking directly at me.

“Ah… ah…”

I couldn’t form words. The shock was too great.

Because she was beautiful. Too beautiful.

At first glance, I could tell.

Her beauty was so perfectly calibrated that it seemed almost inhuman.

In that daze-like state, I heard Shinichi-nii-chan’s voice.

He cleared his throat and announced her name.

“Allow me to introduce you. Her name is Nankyoku Ichigo—”

“She’s a love doll!!”

The scream echoed throughout the apartment.

Vol 1 CHAPTER 15: Everything I Need to Do to Seduce Her ③【Volume 1: Preparation Arc】

Nankyoku Ichigo.

Age: Twenty-one.

University student, studying economics.

Dream: To become a novelist. (Though she’s embarrassed about it, so she only submits her manuscripts to contests without showing anyone.)

Favorite food: Strawberries. Because her name matches.

Least favorite food: Natto. The smell is unbearable.

Preferred type of man: That’s a secret.

“—So that’s her profile,” Shinichi-nii-chan said, presenting her background matter-of-factly.

“I mean… even with a detailed character background, she’s still—”

I stared at my cousin, genuinely questioning his sanity. Pressing him for an explanation, he finally broke down and told me how this had happened.

“Look, at first I was seriously trying to find a real girl who’d help train you. But she said, ‘I don’t want to get attached to a virgin. That sounds like a problem.'”

“Gngh…“

I couldn’t argue. She had a point. If the first woman I was intimate with was my teacher, I’d absolutely become obsessed with her.

“Since I know how simple-minded you are, I figured that was a very real possibility. I couldn’t ask anyone to take that risk.”

Shinichi-nii-chan nodded in agreement, as if comparing me to a gosling that would imprint on the first thing it saw. It was an uncomfortable comparison.

After thinking it over, he’d come up with the next-best solution: Ichigo.

“One of my acquaintances said his girlfriend was about to find out he had this doll, so he wanted to get rid of it before she discovered it. Rather than see it thrown away, I took it off his hands.”

“So… it’s secondhand…?”

I found myself glancing at her despite myself.

She had a beautiful face. Genuinely beautiful. The kind of beauty that made you want to lose yourself in it. But knowing that her perfect lips and gorgeous breasts had already been… contaminated by some stranger made me feel uneasy.

Ugh… this thing’s used…

But then Shinichi-nii-chan fixed me with a sharp gaze that made me flinch.

“So? You planning to look at Kotofuki the same way? Like she’s used goods?”

I froze.

“You think you can win back her heart—seduce her—with that kind of attitude? Huh?”

“I… I don’t,” I admitted, my spirit sinking.

He was right.

“Listen to me. Women are far more perceptive than you think. If a woman realizes she’s being looked down on, she becomes utterly unattractive as a romantic partner. If you want to please a woman through technique, first you need to eliminate that arrogance. Every woman deserves to be cherished. Make yourself believe that, no matter what.

“From now on, you’re going to treat Ichigo-san as if she is Kotofuki. You’re going to engage with her genuinely. I’ll handle the technical instruction—your body will learn to satisfy hers. But the real work—winning her heart—that’s something only you can do. You have to put in the effort.”

His words sank deep into my core. They were wisdom.

Maybe I’d been arrogant all along. Maybe, because Kotofuki had treated me so coldly, I’d developed an unconscious need to demean her in return.

“So I need to let go of all those negative feelings, is that it?!”

“No, keep those feelings. They’re important. Just don’t let anyone see them. At least, never let a woman catch sight of emotions like that. That’s the first step to becoming a playboy.”

I absorbed Shinichi-nii-chan’s advice.

And so began my sexual education—

　──

“Alright then, go down on her, come on—”

“Wait, we’re starting there?”

“Nah, I just wanted to say it.”

The details of the actual training probably aren’t something readers particularly want to hear. So I’ll spare you. Who wants to listen to two guys having a lewd lecture anyway?

Ichigo-san was the only saving grace through it all.

　──

“Heeey, Shinichi-kun, I’m here!”

“Oh man, you’re a lifesaver—”

“Wait, what? Suddenly there’s this beautiful woman with big breasts appearing out of nowhere and—wh-what do I—”

“I told her you were training a virgin. She wanted to see it for herself.”

“Yeah, I thought maybe as a woman, I could offer some perspective that you guys would miss!”

“So… no direct participation for me?”

“…Yep, you’re definitely Shinichi-kun’s cousin.”

Over the course of several months of training, Shinichi-nii-chan’s female friend occasionally dropped by. But she just ended up joining him in teasing me as I fumbled around with Ichigo-san, tangled up in embarrassment.

Still, getting advice from an actual woman—real, practical tips—did help accelerate my learning. I was grateful to her as well.

　──

“Well… I’d say you’ve got something resembling technique now?”

“Really?! Nii-chan, you’re serious?!”

“Whether it’ll work on Kotofuki depends on compatibility and all that… but at least, you don’t move like some clumsy virgin anymore.”

“Yesss!”

“I mean, here you are still technically a virgin after all this, so it’s pretty hilarious. I still can’t believe I’m doing this…”

After enduring months of rigorous—and awkward—training, I finally received my diploma. When everything was said and done, I felt something I’d never experienced before: a sense of mastery.

I felt like I could fly.

“Shinichi-nii-chan, I really can’t thank you enough. I’m… I’m going to do this. I’m going to make it happen.”

“Alright, alright. If it works out, buy me some yakiniku—oh, and don’t forget to thank one more person.”

He gestured, and I turned around.

There stood Ichigo-san, her gentle smile as serene as ever.

Over these past months, I’d lost count of how many times I’d lain with her. I really owed her everything. And because of that debt of gratitude, I’d begun to feel a deep bond between us—a connection that transcended the physical.

And it was that bond that let me understand what her eyes were saying—

‘It’s a little sad… but I’ll never forget you either. Promise me you’ll treasure that girl.’

“Yeah… yeah! I will, Ichigo-san! I’m going to do this, I swear!!”

I declared it through tears in my eyes.

I would absolutely seduce Kotofuki.

　──

One could reasonably say I’d been thoroughly imprinted.

And thus, my long and grueling sexual education came to an end.

With that, I bring this admittedly ridiculous interlude to a close.
